3-10 TM80 Telemetry Monitor Service Manual
Co-channel interference is the most obvious interference for Wi-Fi. The signal
strength of the nearest AP perceived by the wireless monitor must be 20 dB higher
than that of other APs on the same channel. Take 2.4 GHz band as an example. The
following channel deployment is recommended to realize Wi-Fi coverage similar to
cellular coverage.
For co-channel interference, the interference between floors needs to be considered
and the following case should be avoided: a pair of APs is set nearby between two
floors and is working on the same channel. Different SSIDs of the same AP do not
generate co-channel interference (CCI) . CCI from different AP but Same SSID can be
accepted in 2.4G band, but this is highly recommended to be avoided.
3.2.1.2 Requirements for the AP capability
Because the low-power WIFI module is sleeping periodically and the capability for
dealing with wireless data is reduced, it is necessary to use high-performance AP to
enhance the stability of total system. Mindray tested a lot with TM80 and Cisco APs,
the compatibility of Cisco AP is proven good.
